APPARATUS FOR MELTING SNOW.

SPECIFICATION forming part of Letters Patent No. 514,682, dated February 13, 1894.

Application filed March 22, 1893. Serial No. 467,226. (No model.)

To all whom it may concern.-

Beit known that I, GEORGE TROUP McCon- MICK, of the city, county, and State of New York, have invented a new and useful Improvement for Melting Snow, of which the following is a full, clear, and exact description. The object of my invention is to provide practical means for the melting of snow on thoroughfares, so that the snow shall be thoroughly and quickly melted, and so save the time, labor and expense involved in the present'method of shoveling and carting.

To this end my invention consists principally in the employment first: of a'large cylinder or roller with perforated holes and steam attachment, attached by slotted hangers to a portable steam boiler, to be used either as a heated roller, or as a steam ejector; second, of a cylinder or tube in the shape of a horse shoe,-or straight, placed as may be desired, either behind, at the side of, or in front, or under the boiler, these tubes having perforatrons, and steam attachment,-for the purpose of spraying the snow with steam, these tubes being attached firmly to the boiler, or-carriage'; thirdly: of movable cylinders with perforations hung on hinges attached to the portable steam boiler or carriage, and having steam attachment, these cylinders can be raised or lowered at will, and are for the purpose of covering a greater area of snow with the steam sprays.

The invention also consists of the construction, arrangement and combination of parts, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification in which similar letters of reference indicate correspondingparts in all the figures.

Figure 1. represents a portable steam boiler and engine, attached to which by slotted hangv ers, is a roller or cylinder with perforations;

of a cylinder or tube in the shape of a horse shoe, with perforations, firmly attached to the portable steam boiler or carriage; and of a nozzle with one or more perforations attached by flexible tubing or steam hose, to the steamchest of the boiler. Fig. 2. represents a rear View of the portable steam boiler with the two movable cylinders, or tubes, attached by hinges, in position. Fig. 3. is a detailed plan view showing the slide for closing or opening the perforations.

In the form shown in Fig. 1. Ihave the perforated roller or cylinder P attached by the slotted hanger U to the boiler Q, by the bolt Q and the nut V.

X represents the holes or perforations, which may be increased or diminished in number, or size, as may be desired, through which the steam forces itself. These perforations can be placed at any part of the roller or cylinder desired.

c is a slide which opens or closes the perforations, and by means of which the cylinder can be used as a heated roller when the slide is closed, or as a steam ejector when the slide is opened.

0' is a slide similar to 0.

V represents the screw by means of which the perforated roller'or cylinder P is made stationary when used as a steam ejector or sprayer. The cylinder P when used as a roller touches the ground, when used as a steam ejector or sprayer it is drawn forward by the chain U which is attached to the front part of the boiler, this raises the roller or cylinder from the ground.

R is the flexible tubing which conveys the steam from the steam chestA to the cylinder P at the point T.

S is the steam cook or valve by means of which the supply of steam is regulated. The

chain U is attached to the slotted hanger U at the point T. v

In the form shown in Fig. 1, B is the perforated horse shoe cylinder or tubing connected at E by the flexible tubing 0 with the steam chest, or dome, A, at D, the supply of steam being regulated by the steam cook or valve G.

F, represents the perforations in thetubing Bwhich may be placed at any angle and in any number desired,through which the steam ejects, or forces itself upon the snow.

Y is the perforated nozzle attached by the flexible tubing, or steam hose W, to the steamchest A by the steam cock'Z. This nozzle Y is managed bya man upon the ground or upon the platform 0, attached to the portable boiler, or carriage. This view of Fig. l. is aside View and of course all the letters and machinery are duplicated on the other side. This portable steam boiler and engine, or steam carriage, represented in Fig. 1. can be moved by horse power or by steam traction by means of a revolving chain, attached to the axle of the Wheels, and the drive shafting of the engine attached to the boiler.

In Fig. 2 the movable perforated cylinder or tube II is connected at N by the flexible tubing M to the steam chest A by the steamcock, or valve N which also regulates the supply of steam. The perforated cylinder H, hung on the hinge I is sustained and held in position by the hook J hooked to the staple L. The perforated cylinders or tubes H. H. are for the purpose of covering a greater area of snow, and can be raised at will to the vertical position of II by means of the hook J, hooked to the staple L.

B, Fig. 2, is a straight perforated cylinder, or tube, which may be used in preference to the horse shoe shaped cylinder B, in Fig. 1.

In the form shown in Fig. 3, 1) represents the slide closing the apertures in a. By pressing the slide 1), at 0, forward to d, the apertures are fully opened. Of course the apertures, or perforations, can be fully or partially opened, or closed, at will, by the movement of the slide b. This slide can be used in the cylinder B in Fig. 1, and in H H, and B, in Fig. 2, the same as explained in the roller, or cylinder P. in Fig. 1. The steam used, may

be superheated if desired.

By the use of the heated roller, or the steam sprays, by means of the machineryIhave described, the snow and ice can be removed from the streets much quicker, and more thoroughly, and at a greatly reduced cost, than by any method now in use. Thus opening up the streets for traffic and the use of the citizens, much sooner than could otherwise be done.

The garbage and decomposing matter, held by the snow and ice for weeks and even months, under the present system of removing the snow, are liberated at once by the above described steam jets or sprays, and the health of the city thus preserved and pestilence averted.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A perforated roller or cylinder attached to a'portable steam boiler by slotted hangers, and having steam attachment by means of flexible tubing attached to the steam chest of the boiler, and a slide for regulating the opening or closing of the apertures or perforations through which the steam forces, or ejects itself upon the snow, substantially as and for the purposes described.

2. A perforated cylinder, or tube, either straight, or in the shape of ahorse shoe, with a slide to regulate the openings, and having steam attachment, to be used below the boiler in any position desired, substantially as and for the purposes described.

3. Perforated cylinders or tubes with a slide regulating the openings, hung on hinges, capable of being raised or lowered at will, to be used substantially as and for the purposes described.
